Subject: [QGIS-Developer] OTB and QGIS
I found quite "difficult" to had OTB working within Processing. In Linux
I had to install (OTB of course) and another package (otb-qgis) and then
it appears in the Processing providers and seems now working.
This maybe a bug.
Otb-qgis package provides tools to generate descriptor files for otb alogirthms.
OTB processing provider uses this tool only if it cannot find a descriptor file which should be in package by default.
Good news is if there is otb-qgis package installed, it is able to create them on the fly and everything works.
A simple fix would be to add otb-qgis as a dependency to "otb" package. This must be done in debian package control!
> Are there any specific instructions to have it installed, also in Windows environments?
OTB installation on windows is Download and extract zip file from orfeo-toolbox.org/packages/
6.6.1 is latest https://www.orfeo-toolbox.org/packages/OTB-6.6.1-Win64.zip
You can simply change location of OTB-X.Y.Z-Linux64 shown in README.md with your OTB windows archive.
Add download and extract of OTB into qgis windows installer?. Can be optional like GRASS. So windows users won't have to go through any stuff.
> If yes, could it be a good idea to add these instructions in the documentation?
Do you mean in qgis documentation ?
Configuration instructions are detailed in README.md. Maybe this could show as help dialog in qgis ?
Not just for OTB, other providers can benefit from it.
Cheers and thanks
